A water delivery device includes a first conduit section and a second conduit section rotatably coupled to the first conduit section by a magnetic joint. The magnetic joint includes a plurality of magnets that cooperatively define a plurality of rotational positions between the first conduit section and the second conduit section.

A drain system includes a drain body attachable to a subfloor and configured for attachment to a pipe member below the subfloor. A seal component is positionable between the drain body and the pipe member and is arranged to form a seal therebetween. The seal component has a body including open upper and lower ends defining an opening therethrough for receiving a portion of the pipe member. An outer surface of the body defines an interface between the seal component and the drain body arranged to permit a first angular movement between the seal component and the drain body. An inner surface defines an interface between the seal component and the pipe member and is arranged to seal and permit a second angular movement between the seal component and the pipe member, wherein the second angular movement is different than the first angular movement.

A gas pipe joint contains: a connection pipe, a first threaded pipe, and a second threaded pipe. The connection pipe includes a first part and a second part, the first part has a first threaded orifice, and the second part has a second threaded orifice. The first threaded pipe includes a first coupling section, a first nut section, and a second coupling section. The second threaded pipe includes a second nut section and a third coupling section, the second nut section has a second screwing portion, and the third coupling section has at least one second recessed portion and a second groove. The third coupling section has a second shoulder. The second shoulder has a second lower gasket. The first groove has two first loops, and the second groove has two second loops.

A water outlet device includes a ball component. The ball component comprises a ball rod and a ball. Two water ports and a water channel located between the two water ports are sequentially formed in the ball rod. An angle is formed between the directions of the two water ports. The ball is arranged on at least one water port. The water channel penetrates through the ball. The two water ports having an angle formed between water flow directions thereof are formed in the water channel of the ball rod, so that the water outlet direction of the water outlet device can be adjusted to be upward, and the water outlet angle can be adjusted to some extent.

A sensor assembly includes a first sensor window defining a first plane, a second sensor window fixed relative to the first sensor window and defining a second plane different than the first plane, and a nozzle positioned to deliver fluid to the first and second sensor windows. The nozzle is translatable along a first axis, rotatable about the first axis, and rotatable about a second axis transverse to the first axis.

A ball swivel of the configuration typically utilized for pool cleaners includes male and female portions featuring an interposed stopper to minimize an area of engagement between the male and female portions under load, while still sealing and allowing rotational and pivotal motion.

A drain system includes a drain body attachable to a subfloor and configured for attachment to a pipe member below the subfloor. A seal component is positionable between the drain body and the pipe member and is arranged to form a seal therebetween. The seal component has a body including open upper and lower ends defining an opening therethrough for receiving a portion of the pipe member. An outer surface of the body defines an interface between the seal component and the drain body arranged to permit a first angular movement between the seal component and the drain body. An inner surface defines an interface between the seal component and the pipe member and is arranged to seal and permit a second angular movement between the seal component and the pipe member, wherein the second angular movement is different than the first angular movement.

The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.
